Well, technically it isn't that God cannot break his own rules, maybe he can, maybe he can't
The thing to realize here is that if we're going to discuss God in a logical manner, and then posit that God can be illogical, it becomes an exercise in futility. God, therefore, must be a logical being if we are to seriously discuss about God. Otherwise there really is no point in discussing this. This, however, doesn't eliminate the possibility that God can break his own rules. It's just that no one should take this position seriously, if we are to do this in a logical manner.
